The crimping mechanism includes a plurality of jaws configured for coordinated inward movement toward a crimping axis to reduce the size of a GC 7 1. crimping iris around a stented valve. A rotating cam wheel acts on the jaws and displaces them inward. A number of Cartesian guide M elements cooperate with the jaws to distribute forces within the crimping mechanism. The guide elements are located between the e• 1 crimping jaws and an outer housing and are constrained by the outer housing for movement along lines that are tangential to a circle ei ---. centered on the crimping axis. The guide elements engage at least some of the crimping jaws while the rest are in meshing engagement IN so as to move in synch. An actuation mechanism includes a lead screw, carriage assembly and a linkage to rotate the cam wheel with 1-1 © significant torque. ei C [Continued on next page] WO 2017/223486 Al IMEDIMOM0101011MMEMOONEMOMEEROMEHOIMI TM), European (AL, AT, BE, BG, CH, CY, CZ, DE, DK, EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LT, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
